Paper prototyping is a low-cost, structured brainstorming technique that uses materials such as paper and pencils to better understand the way users interact with physical, visual, and textual information. It can help us learn how to better think through workflows, space design, and information architecture. Session attendees will learn about the ways low-fidelity prototyping and wireframing can be used to develop ideas, troubleshoot workflows, and improve learning and interaction. In the first half of the workshop, participants will step through activities in icon design, persona development, and task development. In the second half they will develop a low fidelity prototype and step through a guerilla usability testing process with it.
